Titles already signed up include this years Age of Conan (due in October) and Supreme Commander, with some games already tied to it. The operating system is available in four home versions, boasting an array of interface and security tools, priced between GBP 100 and 250 (EUR 150 and 380. In order to run the operating system, users will need an 800MHz processor, 512MB RAM and a 15GB hard disk as a minimum.
